What is the age of Vindhyan Supergroup?

Although a Neoproterozoic age has often been inferred for the Upper Vindhyan (1), firm geochronologic evidence for this has been missing, and recent paleomagnetic–geochronologic work even suggests a late Mesoproterozoic age (1.0–1.07 Ga) of the uppermost Vindhyan units (2).

How is Aravalli range formed?

These are fold mountains of which rocks are formed primarily of folded crust, when two convergent plates move towards each other by the process called orogenic movement. The Aravallis date back to millions of years when a pre-Indian sub-continent collided with the mainland Eurasian Plate.

Why was the Vindhyan Supergroup important to science?

Deposited in an intra-cratonic basin, it is composed mostly of shallow marine deposits. It is believed to have recorded a substantial portion of Proterozoic time and therefore, likely to contain valuable information on the evolution of the atmosphere, climate, and life on our planet.
